This is really more of a method than an actual recipe. You can add any herbs and spices you like - parsley, thinly sliced fennel or zucchini, basil, mint...you name it! Arctic char, halibut, cod, or haddock would all be great in place of the tilapia. Just make sure the pieces aren't too thick, or you may have to cook it a bit longer. You can check for doneness by taking a little peak in the package with the tip of your knife.
Preheat the oven to 400 degrees and lay out 2 sheets of parchment paper.
Place three slices of lemon on each of the parchment and top with fish.
Season fish with salt and pepper and divide the dill, cilantro, tomatoes, and green onion evenly among the parchment.
Drizzle each parchment with half of the wine, olive oil, and lemon juice and fold up edges to a tight package. Place in the oven for 15 minutes and let rest for about 5 minutes before opening.
